“…The small peak at 1641 cm −1 could be assigned to the O-H of water absorbed from cellulose. [21] In the C-O stretching vibration region, the peaks at 1163, 1111, 1059, and 1035 cm −1 are corresponded to the vibrations of C1-O-C4, C2-O2H, C3-O3H, and C6H2-O6H. [22] Similar to QAFGO, two new peaks at 2852 and 2921 cm −1 have appeared after functionlization reaction, which come from the moiety of DMAOP and confirm the successful functionalization of nanocellulose.…”

electronic insulator with abundant oxygen-containing groups (epoxy, hydroxyl, and carboxyl groups), which can be easily functionalized to improve its ionic conductivity. [12,16] Owing to the wide range of oxygen functional groups on its basal planes and edges, GO is also readily exfoliated to yield well-dispersed solution of individual GO sheets in both water and organic solvents, and then flow-directed assembled into a free-standing paper-like material by vacuum filtration. [12,17] However, despite all the progress of the development of a free-standing GO electrolyte membrane, its advantages are diminished with the difficulty to form a mechanically robust membrane. [17,18] Consequently, that makes the free-standing GO membranes less attractive for being used as practical solid-state electrolytes in energy storage systems. To enhance the mechanical strength, several fillers can be incorporated into GO matrix. Among the multifarious materials, cellulose-the most abundant renewable material-is recognized as a good binder and surface modifier thanks to its low cost, high hygroscopicity, flexibility, ad porous substrate that allows strong binding of other materials. Particularly, considerable interest has been directed to nanocellulose fiber because of its low thermal expansion, high surface area, high surface area-to-volume ratio, strengthening effect, good mechanical and optical properties which may find many applications in nanocomposites. [19] Meanwhile, due to its highly reactive area rich in hydroxyl groups, cellulose can be easily refashioned through a surface-functionalization to conduct ions and be utilized in advanced batteries. [7] Herein, for the first time, we report on a laminate-structured nanocellulose/GO membrane functionalized with highly hydroxide-conductive quaternary ammonium (QA) groups to be applied as a robust solid-state electrolyte in flexible, rechargeable zinc-air batteries. The QA-functionalized nanocellulose/GO (QAFCGO) membrane is fabricated through chemical functionalization, layer-by-layer filtration, cross-linking, and ion-exchange processes (Figure 1a). For the functionalization process, dimethyloctadecyl [3-(trimethoxysilyl)-propyl] ammonium chloride (DMAOP) has been selected as the functional precursor containing QA moieties. The hydroxide conductivity and the alkaline stability in the highly surface-active DMAOP are provided by quaternary ammonium groups which are already attached to this organic compound. Thus, the hydroxide conducting characteristic of the electrolyte membrane can be achieved directly through the precursor DMAOP without complex organic synthesis. First, the trimethoxy groups of trimethoxysilyl are hydrolyzed to form the corresponding silanols, and the hydrolyzed silanols undergo self-condensation to yield silanol oligomers intermediates ( Figure S1, step 1, Supporting Information). Then, these intermediates are adsorbed onto nanocellulose/GO surface rich in oxygen-containing groups through hydrogen bonding ( Figure S1,

“…The transparency slightly drops up to 40% with the addition of 5 wt.% ZnO because of the Rayleigh scattering arising from the occurring nanoparticle aggregation (Althues, Henle, & Kaskel, 2007). The development of CNC-based transparent films which strong UV-blocking properties would further expand the application areas optical transparent nanopapers based on cellulose, which have been mainly limited to touch screens, flexible electronics, solar cells, transistors, antennas and sensors (Barr et al, 2011;Han, Kim, Li, & Meyyappan, 2012;Zhu et al, 2014).…”

Lately, printed oxide electronics have advanced in the performance and low‐temperature solution processability that are required for the dawn of low‐cost flexible applications. However, some of the remaining limitations need to be surpassed without compromising the device electronic performance and operational stability. The printing of a highly stable ultra‐thin high‐κ aluminum‐oxide dielectric with a high‐throughput (50 m min−1) flexographic printing is accomplished while simultaneously demonstrating low‐temperature processing (≤200 °C). Thermal annealing is combined with low‐wavelength far‐ultraviolet exposure and the electrical, chemical, and morphological properties of the printed dielectric films are studied. The high‐κ dielectric exhibits a very low leakage‐current density (10−10 A cm−2) at 1 MV cm−1, a breakdown field higher than 1.75 MV cm−1, and a dielectric constant of 8.2 (at 1 Hz frequency). Printed indium oxide transistors are fabricated using the optimized dielectric and they achieve a mobility up to 2.83 ± 0.59 cm2 V−1 s−1, a subthreshold slope <80 mV dec−1, and a current ON/OFF ratio >106. The flexible devices reveal enhanced operational stability with a negligible shift in the electrical parameters after ageing, bias, and bending stresses. The present work lifts printed oxide thin film transistors a step closer to the flexible applications of future electronics.
